Right on. Pre-rebuild, mine would do the flame routine for about 4 or 5 seconds right after full throttle, in gear, into a corner on the track.
Now, not a flame in sight, ok by me. The on track cars and people in the stands aren't as entertained though

In my case, it might have had something to do with a very leaky intake valve passing unburned fuel out the exhaust --- there are probably several ways this flameage actually occurrs, somehow get the fuel out there and it'll happen, right?
